RBAC, ABAC, and ReBAC (Zanzibar-style) reference with a decision framework, implementation patterns, a segregation-of-duties matrix, and anti-patterns such as role explosion and hard-coded authorization. Use when choosing or implementing an authorization model or fixing IDOR-style ambient authority.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Access Control Models > RBAC, ABAC, ReBAC patterns -- when to use which, implementation guidance, and common pitfalls. ## Knowledge Base ### Access Control Model Comparison | Model | Decision Based On | Complexity | Best For | Weakness | |-------|-------------------|-----------|----------|----------| | **DAC** (Discretionary) | Owner grants access | Low | File systems, small teams | No central control, permission sprawl | | **MAC** (Mandatory) | Security labels/clearances | High | Military, classified data | Inflexible, requires central authority | | **RBAC** (Role-Based) | Assigned roles | Medium | Enterprise apps, most SaaS | Role explosion, coarse-grained | | **ABAC** (Attribute-Based) | User/resource/environment attributes | High | Dynamic policies, fine-grained | Complex policy management, debugging | | **ReBAC** (Relationship-Based) | Object relationships | Medium-High | Social networks, document sharing, multi-tenant | Relationship graph complexity | ### Decision Framework ``` Does access depend on WHO the user is (their role)? YES → Start with RBAC Do you need decisions based on CONTEXT (time, location, device, risk)? YES → Layer ABAC on top of RBAC …

How to install
mdr add hermeticormus/libresecops-claude-code/access-control-models@sha256:b42f829c81873b3eThe line at the top of this page pins the label git:20260930.71a2663, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
